Toolbox 1: Logical

Creativity and logic sometimes seem to be at the opposite ends of the
spectrum. Far from it--logic is the first tool of all inventors. Many
inventive and creative problems have been solved by cold, hard analysis
and thinking. You do not always have to daydream and get into the fluffy
stuff to solve every problem (although this does become necessary for
those problems which do not succumb to the logical approach).
